sql server - copying related data using CTE within one SP? -

-

I have to copy the data for a student (clone student) which includes three tables:

<
  • TblStudent Subjects (where PK is a student student and FK student is Idd)

    1. To complete this, call me

      1. Performing student records by competing with existing student records and getting new students Classes
      2. Create Record student subject to all current students about using new student student and create
      3. Students topic comments recorded using freshman student. Blockquote>

        ... hope you got it

        So, is it a great way to use CTE in a store process? (I am using SQL Server 2005)

    • INSERT and UPDATE statements operate on only one table There are times. You need 3 tables that require INSERTs. You can of course insert several rows in the table in one line, and I think it is good to do it when possible, but you can not put rows in several tables together.

    Think in this way. When you are pulling records in a single result set from several sources, you do the query. When you modify the data, you are pulling records from several sources to apply changes to the same result set.

    Besides, I hate to say this but there are some things that are super-elegant solutions. To ensure that all 3 INSERT statements are in the form of an atomic transaction (all or nothing), your stored procedure needs to implement some best practices, the final result can be vocabulary and fun, but It will be quick, effective, safe, sound and up-to-date.

    After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

    I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

    sql server - How can I determine which of my SQL 2005 statistics are unused? -

    -
    After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
